Monitoring of metal levels in coastal region of Bursa

Bursa is an industrial, agricultural and economically developed city of the Marmara region. It is important to monitor environmental sea pollution that may be caused by maritime transport and the increasing population. Metal monitoring of metal levels in the coastal areas of the Bursa was planned over 42 seawater samples taken from 7 regions of the selected coastline in the 6-month period covering July and December 2017. The traceability of metal ions in seawater makes it difficult to detect because of various interference effects. In the trace metal analysis with Flame Atomic Absorption Spectrometer (AAAS), various enrichment techniques such as co-precipitation, adsorption, solid phase extraction (SPE) and ion exchange are required. In this respect, seawater samples were taken from the coastal region of Bursa; for the simultaneous determination of cadmium, chromium, copper, nickel, lead and zinc metals, 8-hydroxyquinoline was used as the metal chelating agent and the method for the mentioned metals after enrichment in the activated carbon filled column was developed.The validation studies for the developed method were investigated with percent recovery yields by adding 1 mg / L Cd, Cu, Cr, Ni, Pb and Zn to synthetic seawater (ASTM D1141-98). The method was also tested with the help of the commercially available reference material QC-3163. Cd, Cu, Cr, Ni, Pb, and Zn metal concentrations in seawater samples taken from coastal regions of Bursa were determined below the limit of determination (LOD) and legal values. The physical properties of seawater were determined on the spot in the analyses carried out over a period of 6 months.
